Description

Technical Field

[0001] This invention belongs to the field of flat plate pressing and molding technology for building decoration, and relates to a glass magnesium flat plate pressing and molding device and a glass magnesium flat plate molding method. Background Technology

[0002] Magnesium oxide (MgO) flat sheets are a new type of non-combustible decorative material made from a ternary system of magnesium oxide, magnesium chloride, and water, through formulation and modification. It is a stable magnesium-based cementitious material, reinforced with medium-alkaline fiberglass mesh and filled with lightweight materials. The production process includes the following steps: 1) Laying a layer of non-woven fabric on a pallet; 2) Evenly spreading a slurry of magnesium oxide, magnesium chloride, and water onto the non-woven fabric; 3) Laying another layer of non-woven fabric on the slurry; 4) Roll forming, i.e., rolling the slurry on the pallet into a magnesium oxide flat sheet; 5) Cutting, i.e., cutting the rolled magnesium oxide flat sheet to the required length and sending it into an oxygen-curing chamber for curing. To ensure the quality of magnesium oxide flat sheets, the People's Republic of China National Standard GB / T33544-2017 Magnesium Oxide Flat Sheets stipulates corresponding regulations for improving the appearance quality and apparent density of magnesium oxide flat sheets.

[0003] Currently, most glass magnesium oxide flat plate roll forming devices have the following problems: 1) Uneven slurry discharge speed, resulting in large deviations in the apparent density of the processed glass magnesium oxide flat plate; 2) Uneven thickness of the support plate, resulting in large deviations in the thickness of the roll forming template; 3) During the roll forming process, the slurry flows backward, making it difficult to guarantee the apparent density of the rolled glass magnesium oxide flat plate; 4) During the extrusion forming process, scraps are generated, causing serious waste of slurry; 5) During the cutting process, the support plate is easily damaged or the cutting is incomplete, resulting in the problem of "broken threads".

[0004] Chinese patent application number 202210502088.1 discloses a fireproof composite board roll forming device and forming method. To address the problem of scrap material generation and significant slurry waste during the roll forming process of fireproof composite boards, the device installs moving anti-overflow plates on both sides of the template. These anti-overflow plates form a concave mold with the template, reducing scrap material waste to some extent. However, during roll forming, some slurry overflows from the anti-overflow plates, causing further waste. To solve the problem of uneven slurry discharge speed leading to large deviations in the apparent density of the processed fireproof composite board, the device uses a pusher plate inside the hopper to compress the slurry. The slurry is discharged from the strip-shaped opening on the front side of the silo. As the slurry in the silo gradually decreases, the amount of slurry pushed out also gradually decreases at the same pushing speed. It is still difficult to guarantee the consistency of the apparent density of the processed fireproof composite board. In addition, during the roll forming process, the slurry flows backward, making it difficult to guarantee the apparent density of the formed fireproof composite board. To solve the problem of large thickness deviation of the template due to the uneven thickness of the pallet, the device makes fine adjustments to the distance between the roller and the upper surface of the template based on the thickness of the template using piezoelectric ceramic sheets to ensure the consistency of the thickness of the fireproof composite board after roll forming. This structure is too complicated, and the real-time performance of the fine adjustment is difficult to guarantee. Summary of the Invention

[0023] Furthermore, the glass magnesium flat plate forming method of the glass magnesium flat plate pressing and forming device includes the following steps:

[0024] (1) Preparations:

[0025] The nonwoven fabric roll is manually installed on the roll support shaft of the lower nonwoven fabric laying component and the upper nonwoven fabric laying component, and the first gripper of the drag kit holds the front end of the nonwoven fabric.

[0026] (2) Lay non-woven fabric on the pallet:

[0027] When the pallet moves to the nonwoven fabric laying component under the drive of the roller conveyor, the No. 1 motor starts and drives the drag kit to move horizontally along the No. 1 guide bar, pulling out the nonwoven fabric until the length of the pulled-out nonwoven fabric is equal to the length of the glass magnesium plate. The No. 2 gripper of the clamping kit closes and clamps the pulled-out nonwoven fabric on both sides near the roll support shaft. The output shaft of the cutting motor of the cutting component rotates, driving the cutting blade to move, thereby cutting the pulled-out nonwoven fabric and laying the nonwoven fabric on the pallet.

[0028] (3) Overflow prevention components: Place the overflow prevention frame on the tray:

[0029] The piston rod of cylinder No. 7 of the anti-overflow component extends, driving the No. 7 horizontal bar to move down along the No. 7 light bar and the anti-overflow frame installed on it, so that the bottom surface of the anti-overflow frame contacts the tray, and the anti-overflow frame and the tray form a lower mold; motor No. 6 of the moving component starts, driving the No. 6 drive plate and the anti-overflow component installed on it to move synchronously along the No. 6 light bar and the roller assembly line, and the tray and the anti-overflow frame that move with the roller assembly line remain relatively stationary;

[0030] (4) Spread the slurry on the pallet:

[0031] The opening motor of the slurry holding component starts, opening the opening plates symmetrically inserted into the strip grooves on the left and right sides of the hopper; the second motor of the slurry spreading component starts, driving the slurry holding component to swing back and forth on the top surface of the support frame, evenly spreading the slurry in the hopper into the lower mold formed by the anti-overflow frame and the tray; after the slurry spreading in the lower mold formed by the anti-overflow frame and the tray is completed, the opening motor of the slurry holding component starts again, rotating in opposite directions, closing the opening plates symmetrically inserted into the strip grooves on the left and right sides of the hopper, and at the same time the second motor of the slurry spreading component stops, and the slurry holding component stops swinging back and forth;

[0032] (5) Lay non-woven fabric on the slurry:

[0033] When the lower mold moves to the upper nonwoven fabric laying component, the upper nonwoven fabric laying component lays a layer of upper nonwoven fabric on the slurry;

[0034] (6) Compression molding:

[0035] The hydraulic rod of the No. 4 hydraulic cylinder of the pressing and forming component extends, driving the pressing plate to move downward and pressing the slurry in the lower mold formed by the anti-overflow frame and the support plate; the hydraulic rod of the No. 4 hydraulic cylinder of the pressing and forming component retracts, driving the pressing plate to move upward and separating the pressing plate from the pressed and formed glass magnesium plate; the piston rod of the No. 7 cylinder of the anti-overflow component retracts, driving the No. 7 crossbar to move upward along the No. 7 light bar and the anti-overflow frame installed on it, so that the anti-overflow frame separates from the pressed and formed glass magnesium plate. Thus, the pressing and forming of a glass magnesium plate is completed.

[0036] (7) The overflow prevention component returns to its initial position:

[0037] The sixth motor of the moving part rotates in the opposite direction, driving the sixth drive plate and the anti-overflow component installed on it to move along the sixth light bar, returning to the initial position, ready to process the next piece of glass magnesium plate.

[0038] Beneficial effects: Compared with the prior art, the features of this invention are: (1) The entire process of laying the upper non-woven fabric, spreading the glass magnesium plate slurry, laying the lower non-woven fabric, and pressing is automated, which reduces the labor intensity of workers and improves production efficiency; (2) The slurry is spread in the lower mold composed of the anti-overflow frame and the pallet by "sieving", which ensures the uniformity of the slurry spreading, so that the apparent density of the glass magnesium plate is consistent in all positions after molding; (3) The anti-overflow frame is driven to move down by the cylinder to form the lower mold with the pallet, which makes full use of the compressibility of air and avoids the gap between the anti-overflow frame and the pallet or damage to the pallet due to the uneven thickness of the pallet; (4) In the traditional roll forming method, the position of the roll roller is fixed, while the thickness of the pallet is uneven, which leads to a large deviation in the thickness of the template of roll forming. This invention uses a hydraulic cylinder to press the glass magnesium plate. (5) The compressibility of hydraulic oil is fully utilized to solve the problem of uneven thickness of the glass magnesium plate after molding due to the uneven thickness of the pallet; (6) During the rolling molding process, the slurry flows backward and the apparent density of the rolled glass magnesium plate is difficult to guarantee. This invention presses the slurry by pressing the plate and automatically adjusts the height of the anti-overflow frame to make the apparent density of the glass magnesium plate at each position after molding consistent; (7) No scrap material is generated during the glass magnesium plate pressing molding process of this invention, avoiding the waste of slurry; (8) The glass magnesium plate pressing molding of this invention avoids the cutting process required by the traditional rolling molding method and improves production efficiency; (9) By adjusting the position of the two opening plates in the strip grooves on the left and right sides of the insertion hopper and replacing the anti-overflow frame, glass magnesium plates of different sizes can be processed, expanding the application range of the production line.

[0094] A method for forming a magnesium oxide sheet using a magnesium oxide sheet pressing and forming apparatus includes the following steps:

[0095] Step 1: Preparation

[0096] The nonwoven fabric roll is manually installed on the roll support shaft 110 of the lower nonwoven fabric laying component 1 and the upper nonwoven fabric laying component 3, and the first gripper 1022 of the drag kit 102 clamps the front end of the nonwoven fabric.

[0097] Step 2: Lay the non-woven fabric on tray 8:

[0098] When the pallet 8 moves to the lower nonwoven fabric laying component 1 under the drive of the roller conveyor 5, the first motor 109 starts, driving the drag kit 102 to move horizontally along the first guide bar 103 to pull out the nonwoven fabric until the length of the pulled-out nonwoven fabric is equal to the length of the glass magnesium plate. The second gripper 1073 of the clamping kit 107 closes and clamps the pulled-out nonwoven fabric on both sides near the roll support shaft 110. The output shaft of the cutting motor 1066 of the cutting kit 106 rotates, driving the cutting blade 1065 to move, thereby cutting the pulled-out nonwoven fabric and laying the nonwoven fabric on the pallet 8.

[0099] Step 3: Place the overflow prevention frame 706 on the tray 8.

[0100] The piston rod of cylinder 705 of anti-overflow component 7 extends, driving crossbar 703 of number 7 to move down along light bar 701 of number 7 and anti-overflow frame 706 installed on it, so that the bottom surface of anti-overflow frame 706 contacts the support plate 8, and anti-overflow frame 706 and support plate 8 form a lower mold; motor 606 of moving component 6 starts, driving drive plate 604 of number 6 and anti-overflow component 7 installed on it to move synchronously along light bar 602 of number 6 and roller conveyor line 5, so that support plate 8 and anti-overflow frame 706 remain relatively stationary as they move with roller conveyor line 5;

[0101] Step 4: Spread the slurry on tray 8:

[0102] The opening motor 2020 of the slurry holding component 202 starts, opening the opening plates 2028 symmetrically inserted into the left and right strip grooves of the silo 2021; the second motor 204 of the slurry spreading component 2 starts, driving the slurry holding component 202 to swing back and forth on the top surface of the support frame 201, thereby evenly "sifting" the slurry in the silo 2021 into the lower mold formed by the anti-overflow frame 706 and the support plate 8; after the slurry spreading in the lower mold formed by the anti-overflow frame 706 and the support plate 8 is completed, the opening motor 2020 of the slurry holding component 202 starts again, rotating in opposite directions, closing the opening plates 2028 symmetrically inserted into the left and right strip grooves of the silo 2021, while the second motor 204 of the slurry spreading component 2 stops, and the slurry holding component 202 stops swinging back and forth;

[0103] Step 5: Lay non-woven fabric on the slurry:

[0104] When the lower mold moves to the upper nonwoven fabric laying component 3, the upper nonwoven fabric laying component 3 lays a layer of upper nonwoven fabric on the slurry;

[0105] Step 6: Pressing and molding:

[0106] The hydraulic rod of the fourth hydraulic cylinder 405 of the pressing and molding component 4 extends, driving the pressing plate 402 to move downward, pressing the slurry in the lower mold formed by the anti-overflow frame 706 and the support plate 8; the hydraulic rod of the fourth hydraulic cylinder 405 of the pressing and molding component 4 retracts, driving the pressing plate 402 to move upward, separating the pressing plate 402 from the pressed and molded glass magnesium plate; the piston rod of the seventh cylinder 705 of the anti-overflow component 7 retracts, driving the seventh crossbar 703 to move upward along the seventh light bar 701 and the anti-overflow frame 706 installed on it, so that the anti-overflow frame 706 separates from the pressed and molded glass magnesium plate. Thus, the pressing and molding of a glass magnesium plate is completed.

[0107] Step 7: The overflow prevention component 7 returns to its initial position.

[0108] The sixth motor 606 of the moving part 6 rotates in the opposite direction, driving the sixth drive plate 604 and the anti-overflow part 7 installed on it to move along the sixth light bar 602, returning to the initial position, ready to process the next piece of glass magnesium plate.
